Do you have the original regulator? If it's OEM Kohler there is a part number on it.after calling parts tree they gave me the number kohler and after going through the auto system it gave me the address to a local dealer, so i called them and they could not tell me, so they are calling kohler and i'm on hold lol
this is a mess this morning . i called parts tree they list two different Rectifier-Regulator
